Disappointing discovery for those looking to tune their Fusion Sports.

The 2.7 Ecoboost in the F150 has some impressive gains when applying just a tune (Stage 1). The second vehicle to use the 2.7 Ecoboost was the Ford Edge Sport. That vehicle had some huge gains just for stage 1 that easily surpassed those seen for the F150 application of the 2.7 Ecoboost. While they are essentially the same engine there is one seemingly minor difference that actually makes a huge different when venturing into the quest for more power. If you read the detailed specs for the engine you will notice a difference under fuel delivery.

F150 – direct injection
Edge Sport – direct multi-shot injection

Tuners are pointing to the fuel delivery system as the reason why the gains are much higher for the Edge Sport.

Now the bad news. I assumed, given that they are corporate cousins, that the Fusion Sport would share all of the same engine specs as the Edge Sport (other than maybe a different final factory tune). The power ratings seemed to align with that. However, that is actually not the case as the Fusion Sport is not getting the direct multi-shot injection used on the Edge Sport (side note, the 3.0 Ecoboost MKZ will use direct multi-shot injection as well).

What does multi-shot do? I am unable to find a definitive answer other than some patents, etc. But it looks like it is able to inject fuel at “non-standard” times to help with emissions, detonation control, etc.

So I would expect F150 2.7 Ecoboost-like gains if you go the tuning route. The end of the world? No. But personally disappointing? Yes (for me at least).

One a final note. I am also stuck on why only use multi-shot on the 2.7 in the Edge Sport and nowhere else (F150, MKX, Fusion, etc.)?

While that's certainly possible, I'd find it unlikely. Manufacturers (and Ford is no different) generally prefer a commonality of parts, especially in something as complex as engines. I'd expect that the issue is simply differing descriptions put out by different product teams describing the 'features' of each engine.

Now it's possible it's an ECU/software change to enable 'multi shot', but that seems unlikely to me as well. The Edge Sport doesn't have anything (on paper) than the Fusion. The mileage, power, acceleration (as far as we know) are all the same or worse than the Fusion Sport (as you'd expect from a heavier vehicle).

Like what nlaak said that's what they prefer to do and it's happening even more these days with all the brands that have merged together, now you have FCA that can share a lot of parts across a number of brands and I bet Ford is doing the same thing from Ford to Lincoln.

Yeah, related to that, it's my understanding the 3.0l TT v6 in the MKZ, which is labelled as a Lincoln exclusive is only an exclusive for a 'while'. It will eventually come to Ford. Probably ultimately as a replacement for the 3.5L would be my guess.

I feel the exact same way. Linking to my last comment in my first post. Why build 2.7 Ecoboost engines and change anything but the ECU software? From a cost effectiveness standpoint it doesn't make sense to add something "extra" or "different" to just the Edge Sport engines.

From what I understand, "multi-shot" is not really there for its performance benefits (I think it is merely happenstance that it has a performance benefit when aftermarket tuning is applied). I will add that the ~200 lb. heavier, +20 hp / +30 tq Lincoln MKX (which is listed as having direct injection instead of the Edge Sport's "multi-shot") is a good bit slower than the Edge. More so than it should be on paper. Not sure if the fuel delivery method is a factor there.

But the assertion that the Edge Sport produces more power than the 2.7 Ecoboost F150 (which starts with higher stock numbers) when a Stage 1 tune is applied is a fact. It is ~30whp / ~30wtq over the F150.

Also, the mileage and acceleration better not be the same for a stock Fusion Sport and stock Edge Sport. As far as I am concerned a stock Fusion Sport better be able to hold its own against a Stage 1 Edge Sport (0-60:4.8 sec. / 1/4 Mile: [email protected]) or I will personally see it as a failure.

Agreed.

I think Ford was the first to start some mud slinging in saying the Fusion will have 5 more horsepower than the new BMW 340. Car and Driver has the BMW at 4.8 0-60 and 13.3 1/4 mile. Those could be tough numbers for the Fusion to beat. Hopefully they didn't start the mud slinging too soon. My personal hopes are than the Fusion can pull a sub 5 0-60 stock (4.99 is fine) and a sub 13 quarter with Stage 1 tune (12.99 is fine).

I am on board with your train of thought.

I am hoping/expecting to see high 4's to 60 and mid 13's in the 1/4, stock. The Accord V6 sedan runs 5.6 / [email protected] If the Sport can't soundly beat that then all that bloviating about more power than a BMW 340i will make Ford look like a joke.

I expect low 4's and high 12's for a stage 1 tune.
